2. The method of claim 1 wherein the discarding further comprises:, determining, by the computing device, a relative scale between the two images, based on the set of respective ratios; and, determining, by the computing device, a selected feature pair to be discarded from the set of feature pairs based on the determined relative scale and based on the ratios that were determined using the selected feature pair.

4. The method of claim 1 wherein said received set of feature pairs is generated based on a similarity between descriptors.

5. The method of claim 4 further comprising a preliminary filtering step based on a difference between a best and a second best descriptor similarity score.

6. The method of claim 1 wherein said discarding feature pairs is based on a histogram of the set of respective ratios and further determining a scale between the two images based on the histogram.

8. The method of claim 7 wherein said received set of feature pairs is generated based on a similarity between descriptors.

9. The method of claim 8 further comprising a preliminary filtering step based on a difference between a best and a second best descriptor similarity score.

10. The method of claim 7 wherein said discarding feature pairs is based on a histogram of the set of respective ratios and further determining a scale between the two images based on the histogram.

11. The method of claim 7 wherein said discarding feature pairs is based on a histogram of the set of respective differences of angles and further determining a rotation between the two images based on the histogram.
